Ingaruka za selile ether kuri tile imeza

Sima ishingiye kuri tile ifata nicyo gikoreshwa cyane kuri minisiteri idasanzwe yumye. Nubwoko bwibinyabuzima cyangwa unoruvanike hamwe na sima nkibikoresho nyamukuru byogumya kandi byugarije amanota, ushinzwe kugumana amazi, imbaraga zamazi, imbaraga zambere na lated. imvange. Mubisanzwe, bigomba gusa kuvangwa namazi. Ugereranije na pertable isanzwe, irashobora kunoza imbaraga zumuyobozi hagati yibikoresho byugarije hamwe na sustrate, bifite imitungo myiza yo kurwanya no kurwanya amazi meza no kurwanya ubushyuhe. Irakoreshwa kandi kumitako yubumwe bwimbere kandi bwo hanze, amabati hamwe nibindi bikoresho byo gushushanya. Byakoreshejwe cyane mu mitego yimbere nigorofa, amagorofa, ubwiherero, igikoni, nibindi ni Tile nyinshi. Ibikoresho.

Mubisanzwe, iyo duciriye urubanza imikorere yubukorikori, dukwiye kwitondera imbaraga za mashini no gufungura igihe cyongeyeho imikorere yacyo nubushobozi bwo kurwanya. Usibye kugira ingaruka kumiterere yimiterere ya reberi ya porcelain, nkuburyo bwo gukorana, imiterere yicyuma cyo gukomera, nibindi, ether, ether ether ifite ingaruka zikomeye kumiterere yubufatanye.

1. Fungura igihe
RyariIfu yoroheje polymer polymerkandiselile etherCodeus mu miseri ya pertar, zimwe na zimwe zamakuru zerekana ko ifu ya rubber ifite imbaraga za kinetic zifatanije nibicuruzwa bya sima, kandi ubumwe bwa selile burahari mumazi yinyamanswa, bigira ingaruka kuri byinshi. Viscozetity no gushiraho igihe cya minisiteri. Impagarara z'ubuso bwa selile ether nini kuruta iy'ifu ya rubber, kandi ikungahaye ku bushobozi bwa selile ku mikoreshereze ya mirtar ingirakamaro gukora ingwate hagati yubuso bwuzuye hamwe na selile.

Mu miseri ya minisiteri itose, amazi yo muri minisiteri arahinga, ether ya selile irakungahaza hejuru, kandi filime ikorwa hejuru ya minisiteri mu minota 5, igabanya umubare wakurikiyeho, nkuko amazi arenga, kuko amazi menshi ari menshi kuva kuri minisiteri. Igice cyo kwimuka kumwanya muto wurugero rwa mirtar, gufungura kwambere kwa membrane bishonga igice igice, kandi kwimuka kwamazi bizazana selile ether hejuru ya minisiteri.

Igenamiterere rya filime ryakariro Ether ku buso bwa minisiteri rifite uruhare runini mu mikorere ya minisiteri:
Ubwa mbere, firime yashyizweho ni inanutse cyane, izashonga kabiri, ntishobora kugabanya imyambaro y'amazi, gabanya imbaraga.
Icya kabiri, firime yashizweho ni ndende cyane, kwibanda kuri selile ether mumazi yamagambo ya mirtar ari hejuru, kandi viscosiya ni nini. Iyo tile yashizwe, ntabwo byoroshye kumena firime yo hejuru.
Duhereye kuri ibi, byunvise ko filime ikora ibintu bya selile ether bifite uruhare runini mugihe cyo gufungura. Ubwoko bwa selile ether (HPMC,Hemc, MC, nibindi) Nurwego rwo Gusohoza (urwego rwo gusimbuza) rugira ingaruka ku buryo bwo gukora fillete ya selile ya selile, nubukomere nubukaze bwa firime.

2, imbaraga
Usibye gutanga imitungo itandukanye y'ingirakamaro yasobanuwe hejuru na minisiteri, ether ether itwara hydration kinetike ya sima. Ubu butegetsi ahanini biterwa n'akagari ka selile ether molekile ku byiciro bitandukanye by'imicure ya simalike muri sisitemu ya simalike, ariko muri rusange, muri rusange, muri rusange, muri Csh na Calcium hydroxide. Ku gicuruzwa cya shimi, ni gake cyane bihimbazwa ku cyiciro cya mbere cya clinker. Byongeye kandi, kubera ubwiyongere bwikigereranyo cyigisubizo cya Pore, Ether yagabanije kugenda kwa Ion (Ca2 +, TER42-, ...) Mubisubizo bya Pore, bityo bikaba bikatirira inzira yo gukumira.

Viscozetity nubundi butaka bwingenzi bugereranya imitungo ya selile. Nkuko byavuzwe haruguru, viscozetity igira ingaruka ahanini ku bushobozi bwo kugumana amazi kandi kandi igira ingaruka zikomeye ku gikorwa cya minisiteri nshya. Icyakora, ubushakashatsi bwageragejwe bwasanze ubukuru bwa selile ether nta ngaruka bufite ingaruka kuri hydration kinetics ya sima. Uburemere bwa molekile bufite ingaruka nke kuri hydration, kandi itandukaniro rinini hagati yuburemere butandukanye bwa molekile nin min 10 gusa. Kubwibyo, uburemere bwa molekiri ntabwo ari ikintu cyingenzi cyo kugenzura svament hydration.
Ati: "Gushyira mu bikorwa selile ether mu bicuruzwa bishingiye ku mibiri ya sima. Bivuga neza ko kudindira ubudahangarwa bwa selile biterwa n'imiterere ya imiti. Ikirangantego rusange cyavuganye muri make ni uko kuri Mhec, urwego rwo hejuru rwigicucu, ruto rwadindikishwa na selile. Byongeye kandi, gusimbuza hydrophilique (nko gusimbuza HEC) birakandamizwa kuruta gusimbuza hydrophobic (nko gusimbuza mh, MHC, MHPC). Ingaruka zidindiza za selile ether igira ingaruka cyane cyane kubipimo bibiri byubwoko hamwe nitsinda ryitsinda ryasimbuwe.
Ubushakashatsi bwacu bwa sisitemu nabwo bwasanze ibikubiye mubasimbuzi bigira uruhare runini mu mbaraga zubukanishi. Twasuzumye imikorere ya HPMC hamwe na dogere zitandukanye zo gusimburwa muri tile imeza, kandi igerageza ether ether impande zombi zifite amatsinda atandukanye. Ingaruka zumutungo wa mashini wizihiza, ishusho 2 nishusho ya 3 ni ingaruka zimpinduka muburyo bukoreshwa na hydroxyPropoxy (ms) ibirimo kurugero rwubushyuhe.

Mu kizamini, turasuzumaHydroxyPropyl Methyl Cellulose (HPMC), nikintu gikomeye. Kubwibyo, dukwiye gushyiramo imibare yombi hamwe. Kuri HPMC, dukeneye itangwa ryo kwemeza amazi no kwaguka. Tuzi ibikubiye mubasimbuye. Igena kandi ubushyuhe bwa Gel ya HPMC, igena ibidukikije HPMC ikoreshwa. Kubwibyo, ibikubiye muri HPMC ikoreshwa nayo irashirwaho murwego. Nigute ushobora guhuza uburyo na hydroxyproxy matsinda muri uru rwego kugirango ugere kubisubizo byiza nibyo twiga. Igishushanyo 2 cyerekana ko murwego runaka, kongera uburyo bugeraho bizazana icyerekezo cyo kumanuka cyimbaraga, mugihe ibikubiye muri hydxylexyl bizokwiyongera kandi gukurura imbaraga ziziyongera. Kumwanya ufunguye, hariho ingaruka zisa.
